For your shifts, you can pick one or both. There tends to be a lot of people who want to do the first shift so they can attend the evening show (or they don't want to be up late).
If you volunteer for the evening show, there'll be specific time off to sample products. And you can always come for the afternoon tasting.
I'm also going to be weighting the volunteer goody bags in terms of awesomeness in this order: (1) both shifts, (2) evening shift, (3) afternoon shift.
I could also use 3-4 people to come early to help put together volunteer gift bags and do other general volunteer prep.
Select whatever applies:
